Selecting Minimum/Maximum Noise Frequencies for Transient Noise Simulation (Download)
Controlling noise is critical when it comes to designing advanced analog and radio-frequency (RF) circuits. In the digital world, designers tend to tackle noise by adding ground planes, shortening high-speed traces, and placing decoupling capacitors close to IC power pins.
However, high-performance analog designs have significantly tighter noise margins. The most important performance metrics in these scenarios — such as signal-to-noise ratio (SNR), bit error rate (BER), phase noise, and timing jitter — rise or fall with noise.
